IPC: H01L21/60
Filed: 1991-04-24
Abstract: PURPOSE:To obtain stabilization at the time of mounting in relation to a semiconductor chip and the manufacture and mounting thereof. CONSTITUTION:An entitled semiconductor chip 21 is characterized in that conductive grains 9 are pressure-connected to the bumps 10 to be connected to the electrodes 24 of a mounting board 23. A metal harder than the dumps 10 is used for the conductive grains 9. When such a semiconductor chip 21 is to be manufactured, the bumps 10 are pressed on a resin film 22 containing a large number of conductive grains 9 so as to pressure-connect the conductive grains by the press force followed by melting the resin film 22. When such a semiconductor chip 21 is to be mounted, an adhesive 26 is applied to the mounting board 23 and the bumps 10 are connected to the electrodes 24 through the conductive grains 9 followed by hardening the adhesive 26 and fixing the conductor chip 21 to the board 23.

Title: Fuel cell power generating system
Inventor: TAKEDA ATSUSHI
IPC: H01M8/04
Filed: 1989-04-11
Abstract: PURPOSE:To reduce remaining voltage and to stop a system without giving an adverse effect on the system by changing the resistor for remaining voltage discharge to a high value and by combining with a zero voltage closing type switch. CONSTITUTION:By a stop instruction, a switch 3a is opened to separate a resistor 2a from a line and a switch 14 is closed to connect a high resistor 13 for remaining voltage discharge to the line. Since the high resistor 13 has higher resistance compared with resistors 2a-2c, consumption current is small and oxygen and hydrogen left inside a cell are gradually consumed, and remaining voltage is also gradually discharged. The remaining voltage is reduced and a system is quickly stopped without giving an adverse effect on a cell 1.

Abstract: PROBLEM TO BE SOLVED: To shorten the manufacturing time of a semiconductor device by simplifying the manufacturing process of the device by flattening the surface of a semiconductor substrate by using hydrogen annealing after the internal surface of a trench formed into the semiconductor substrate is nitrified and polycrystalline silicon is selectively grown on the nitrified internal surface of the trench. SOLUTION: After a trench 10 is formed into a semiconductor substrate 1, a silicon nitride film 2' is formed on the internal surface of the trench 10 while a mask oxide film 3 is left on the surface of the substrate 1. Then polycrystalline silicon is selectively grown on the surfaces of nitride films 2 and 2' exposed in the trench 10 and buried polycrystalline silicon is formed in the trench 10. Namely, the trench 10 is completely filled up by growing the polycrystalline silicon 4 until the surface of the silicon 4 reaches the silicon oxide film 3. Then the film 3 is removed and the surface of the substrate 1 is flattened. At the time of flattening the surface of the substrate 1, hydrogen annealing can be used for melting the surface of the silicon.  Therefore, the manufacturing cost of a semiconductor device can be reduced, because the manufacturing process of the device can be simplified and the manufacturing time of the device can be shortened.
